Abstract: Standing 153mm tall, the HP-1216B heatsink is equipped with a single no-name 120mm fan that rotates at 2000-1000RPM and is illuminated by four blue LEDs. At full speed it's moderately audible, and at the slowest speed you'll get good performance a nearly silent levels.

*Heatsinks are ranked according to the 150W thermal
test results column (rise over ambient temp.). Low temperatures with low
noise levels are considered best. For reference heatsinks with
variable-speed fans, only the high speed (12V) fan test result is included
in the comparison sheet; more detailed results reside in each specific
heatsink review.

The heat
output from Intel processors varies, so Frostytech tests with two thermal values
that represent the upper limits of existing CPU families.

With a 150W heat load applied by the Intel LGA775
version of FrostyTech's synthetic thermal test platform first, the XtremeGear
HP-1216B heatsink maintains a temperature result of 18.8°C over ambient
(54.0dBA noise) at full fan speed.

The XtremeGear HP-1216B heatsink was
next tested on the Frostytech Mrk.II synthetic thermal test platform with an 85W
heat load. Under these test conditions the heatsink had no problem maintaining a
CPU die temperature of 13.8°C at stock fan speed and 16.3°C at 1000RPM.

XtremeGear has a slightly rough around the edges
but very economical, well performing exposed heatpipe heatsink here. It
doesn't run quite as cool as 3Rsystem's Iceage 120 Boss II model, but at half
the price and in general 3-7°C warmer operation test-for-test, it's likely
to quickly find a following.

As with the original, the little rubber feet used
to hold the fan in position are badly designed and will quickly fall out of
position with modest vibration. Best advice is to jerry rig an insulated wire
tie to keep the 120mm fan firmly attached.
